What is the primary purpose of the National Integrated Ballistics Information Network (NIBIN)?

The primary purpose of the National Integrated Ballistics Information Network (NIBIN) is to analyze and compare ballistic evidence. NIBIN is a crucial tool for law enforcement agencies, as it allows them to capture and store digital images of firearm-related evidence, such as bullet casings and marks made by firearms. By comparing these images, investigators can identify links between different crime scenes, individual firearms, and potentially solve firearm-related crimes. This capability significantly enhances the efficiency and accuracy of investigations involving gun violence, making it a vital component in the fight against crime.

Other options, while relevant to law enforcement, do not reflect the specific function of NIBIN. Tracking drug-related crimes, maintaining criminal records, and cataloging missing persons do not involve the forensic analysis of ballistic evidence, which is the central focus of NIBIN.
